also would like to point out u said the lm301h which if u get them from hlg their just lm301b and imo 301h is a marketing ploy

I would guess so here it is word for word "Quantum Board ® QB 288 V2 Bspec are made USA by Horticulture Lighting Group. Each board has 272 highest flux and lowest voltage bin Full Spectrum LM301B LED and 16 470nm Blue LED to enhance spectrum for unbeatable veg performance."
I will be getting like 3 of these pretty soon going to do that for a 4x4 on a 320 driver

Whats the primary white k temp on these?
With no added red (important for veg too) i hope there's some in the K temp.
5k BSpec combined w/ some 660 & tiny 730 would veg allot better. Especially if HLG is to get away from the Bonsai Effect that has been known to impede growth/yields.
We see how high red & blue burples veg, 3k-6k, MH, enhanced White, even hps. Why wouldn't they take the combined info & make a veg light next level? Including the damn UVA strips somehow too.

I thought the difference between b and H was they were more water resistant?

edit after seeing this vid im not sure

Samsung lm301b or lm301h?

Hi everyone, i've been a lurker for quite a while here and seeing more and more grower switching to LEDs! I'm in the process of upgrading my old 250watt HPS grow light to a quantum board and was originally looking at the samsung lm301b diodes but while I was researching I learned that Samsung...

They're exactly the same diode. Come off the same line. Just splits at the end going into H box for horticultural markets showing output in micromoles and the B box for the lighting/decorating industry showing output in Lumens.
Both have antisulfurization coating and are flip chipped. They're not just identical, or similar, or any other word to express it.
They ARE THEE SAME EXACTLY JUST LABELED DIFFERENTLY for different markets.

besides all this though, i just got my bspec 288 board and it is rocking my veg tent and I think Ive put them too close and maybe watered too little but I just have to modify the hanging wires or something to make it hang a little higher, cause my 2x4 with the 1- bspec (130w or something kit?) and two mars shitty 100 w or something boards seem to be frying these girls without warming them up. My flowering tent is ok but my veg game is lacking so I am looking forward to the blue boards but .. I think since going LED my veg game has changed a little bit
